Abstract: A velocity ambiguity resolving method and an echo signal processing apparatus are provided. The method includes: calculating, for first echo signals respectively received by at least two receive antennas in the N receive antennas, a first estimate of a direction of arrival formed by the at least two receive antennas and a first target, where the first echo signals are echo signals formed after transmit signals sent by a same transmit antenna in a time division transmit mode are reflected by the first target; separately performing, by using the first estimate, angle compensation on M second echo signals received by a first receive antenna, to obtain M first compensated echo signals; and performing velocity estimation based on at least two first compensated echo signals, to obtain a velocity of the first target.

Abstract: Examples of the present disclosure provide a channel access period allocation method. The method includes: receiving, by an access point (AP), first information sent by a first station (STA) for requesting a dynamic service period (DSP) from the AP; and sending, by the AP, second information to the first STA to instruct the first STA to send a data frame to the AP in a first DSP, where a start time of the first DSP falls within a first preset time period following an end time of an SP of the first STA, and the first DSP requested by the first STA is pre-allocated to a second STA having a priority that is lower than that of the first STA, where a time delay of the first STA for sending the data frame to the AP satisfies a time delay requirement of a quality of service QoS in the first preset time period.
